Cells can be described as photovoltaic even when the light source is not necessarily sunlight (lamplight, artificial light, etc.) Photovoltaic cells are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
Cells can be described as photovoltaic even when the light source is not necessarily sunlight (lamplight, artificial light, etc.) Photovoltaic cells are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
The operation of a photovoltaic (PV) cell requires 3 basic attributes:
